Auxiliary fuel tank

[Rangerman40]

Anybody have one in their bed? I hate stopping for fuel every 250-300 miles and dealing with gas stations that are less than RV friendly. Thinking of picking up a 60gallon or so tank to extend my range out to 800 miles or so and then I can fuel up on my terms. Just wondering what your experiences have been with them, or brands you may recommend.

I also have an RDS tank with the gravity flow system. They sell an install kit that includes the check valve which stops back flow. There is also a manual on/off valve on the tank. I believe in KISS.

I got the 40 gallon tank/tool box combo which fits below the rails so I can also have a bed cover. If I was doing it over I would get the 60 gallon (?) tank with the smaller tool box. It has the same footprint.

Northern Tool sells them. I suggest going to the RDS site to view all the possible tanks (there are lots). I have even read they will custom make one but have not confirmed that.

Why would you go with the 60 gallon ? I'm looking at the 40 gallon right now.

I had a couple different reasons:

1. I can't get 40 gallons into that tank. Closer to 35. Admittedly not a huge difference but I wavered between the 40 and 60 to begin with.

2. I found I really don't need as large a tool box and could easily get by with the smaller one in the larger tank/toolbox combo, especially since they both have exactly the same outside dimensions.

I bought the tank primarily because I wanted an aux fuel tank. The toolbox was a secondary consideration. I now assume I could only get about 55 gallons into the 60 gallon tank and I'd rather be able to carry 55 as opposed to 35 gallons.

I installed a 35 gallon tank in the bed of my truck that I purchased at Tractor Supply for $299. It is steel and has two bungs, one on each side that I secure with pad locks. It is the same width and height as the truck bed and only ten inches front to back. I have a full size Tractor Supply tool box mounted between the tank and 5th wheel hitch (did mention that I have a long bed?). The tank is plumbed like all other gravity feed tanks with an adapter I purchased at Northern Tools for $60. Because I was concerned about dirt and water infiltrating the auxiliary tank, I installed an in line WIX diesel fuel/water separator filter and a low pressure diesel fuel pump toggled to the drivers cab, adding another $100. Total investment is less than $500. and it works great. Pulled my fiver from Nashville to Kansas City before I needed fuel.

Another vote for the RDS gravity feed tank. We've had ours for over 4 years now, I had to pull it out of the old truck and instal in the new truck, we LOVE it!

The install kit you'll have to get for the tank comes with a check valve, I haven't yet had an "over - flow" situation!

It's nice to be able to get fuel when it's convent for you and not when you "have" to get it. Like B. O. stated I usually get the trailer situated at the CG then take a run for fuel if I need it, Sure is nice not having to be concerned with pulling the trailer through the fuel islands.

You are correct sir! Someone had to say it!

I had two aux tanks (two separate trucks) before selling my 5th wheel.

I went expensive (partly because my read of regulations is different than some and partly because I wanted convenience) and went with American Tank in Frisco, Texas. Their setup is plumbed into the diesel fuel system and into the guage....just flip a switch and you are feeding (and reading) either the main tank or the aux tank.

I went with 95 extra gallons that with the stock tank gave me circa 140 gallons in the truck...effective range even when towing a big-a** 5th wheel of over 1000 miles.

No, I can't pull for 1,000 miles straight. No dog, but the wife can't ride for 1,000 miles either. .......but it's one thing to pull into a lot to stop vs having to pull a 20' truck plus a 40' 5th wheel up to a gas pump. The aux tank allowed me to fuel up in the evening sans trailer....incredibly convenient.

The ones I have installed have a check valve installed in the filler pipe. Shuts off fuel to stop it from running out cap.

Well, I'm 33, have no dogs in tow, and from past experiences realize most of my family can hold it longer than every 250 miles that I currently have to stop to get fuel. So yes, it's very worth it to me.

Any opinions on Transfer Flow?

Transfer Flow have lots of supporters, but they cost a whole lot o'money. I went cheap with mine and used the money I saved to go RV'ing with. 🙂

You'll never save money with this and who cares cause once you're this old yer bladder don't last as long as a tank of fuel anyway......plus yer little sh t eater dog will tear up the upholstery if you don't walk him every 2 hours.........so a transfer tank is a total waste!

I had to laugh a little reading this and then reading your signature. Lol

So are RVs when compared to hotels but we do it anyway.
